No long write-ups this week, just a short list of some great resources that I've found very inspirational and thought provoking. I've broken these resources up into two lists: Blogs and Presentations.
The blogs listed below are ones that I subscribe to and are filled with some great posts about capacity planning, scalability problems and solutions, and distributed system information. Each blog is authored by exceptionally smart people and many of them have significant experience building production-level scalable systems.
Nati Shalom's Blog: Discussions about middleware and distributed technologies
All Things Distributed: Werner Vogels' weblog on building scalable and robust distributed systems.
High Scalability: Building bigger, faster, more reliable websites
ProductionScale: Information Technology, Scalability, Technology Operations, and Cloud Computing
http://www.iamcal.com/ (the "talks" section is particularly interesting)
Kitchen Soap: Thoughts on capacity planning and web operations
MySQL Performance Blog: Everything about MySQL Performance
The presentations listed below are from the SlideShare site and are primarily the slides used to accompany scalability talks from around the world. Many of them outline the problems that various companies have encountered during their non-linear growth phases and how they've solved them by scaling their systems.

If anyone knows of some that I've missed (I'm sure there are many), please list them in the comments and I'll add them to the lists above.
